\ ,6 Claims; (ohm-1 79) 4 This invention relates to casementwindows.

One object of the invention-is to provide a casement window, embodying aniongotherchar acteristics, a strong and durable mounting:

whereby the window may beswung to various positions, for ventilating purposes and to aposi tion such as will permit ready and easy access to both the inner and outer sides when open' for cleaning purposes from the inside of abuilding orroom. Y l :3

Another object of the invention resides in the provision of a casement window embodying a' simple, durable, economical and effective mount v ing means for the window'and which may be readily controlled in'movement to variou s'ad justed positions and which may be easily latched in open or closed positions. g

' A still further object of the invention resides in the provision of a simple mounting for a casement window whereby the window and its su porting means may have relative swinging; and sliding movement and the window swung "bodily entirely away from the window casing or frame to various angular positions withjrelation to the latter for ventilating or window'cl eaning purposes With these and other objectsin view, theQin vention consists in the construction and 9 novel combination and arrangement ofjparts herein-t after described, illustrated in the accompanyingdrawings, and set forth in the claims hereto ap pended, it being understoodthat various-changes in the form, proportion, size and minor details of construction, within thefscope of the claims, maybe resorted to without departing from the spirit of the. invention or sacrificing any of'the advantages thereof. Inthedra'wings:" a Fig. 1 is a front elevation of a casement window in accordance with the present invention, looking from the inside of 'a room or buildingand the window closed.

Referring now more particularly'to the accompanying drawings, the reference character Airidicates a window frame of any size and'composed'of wood or any other suitable material and 10 B" indicates a window sashfor the frame and which may be'composedj of wood or any other suitablematerial and havingone or more window panessecured therein in' any well known manner.

As illustrated, the window sash is composed of theop'posite-side members I and 2 connected at their upper ends by the top sash member 3 and connected at'the'irlower ends by the lower sash member 4, there being shown the vertical and 2Q horizontal intermediate ribs 5 and 6, respectively, whereby;-- in this instancato provide the window with fourwindow panes I. The window sash maybe subdivided, depending upon how many panes 1 maybe desired. 5

The sidemembers I and 2 of the window sash are provided with the usual window stops 8 and 9, respectively, there-being stops I0 and II 'secured to or formed with thetop and bottom sash members- 3 and 4, respectively. I

The lower stop member ll of the lower frame member or 'sill '4 maybe cut away, as at I2, and the adjacent side member of the frame or casing A may'berecessed as at 13, to receive the outer end of a l-metallic or-other, preferably channeled; guide me'mber- H disposed longitudinally of the window sill 4 and-secured to the window sill inthecutaway portion I! of the window sill stop member-l l by means of screws 15 or in any other-suitablemanner. H i Y 40 A slide l6-is adapted to move along the guide [4. This slide l5 has a'recess [6 in one side forming opposite shoulders 16a. A spring l1 of flat material and bowed is located in said recess lGa to travel with the slide l6 and offer frictional resistance to the slide in the guide member I 4; 3 A relatively heavy horizontally disposed window carrying bracket 0 is pivoted at one end, as at l8; to-th'e slide-IGQand it is 'slidably mounted on the inner side of the lower window sash mem ber 4. 1 For instance; the 'bracket C consists of theangularly disposed rnembersB and 20 and thememberlll a't one end-extends beyond the member N, as at 2'I,"and=it;is at this extended end II that the brack'et C- is pivoted at l8 to said' slide l6, whereby the extended end 2| of the bracket C and the slide l6 and the pivot l8 may extend into the aforesaid recess l3 of the window casing when the window is closed.

The member IQ of the bracket C is mounted over the plate 22 fixedly secured by suitable fastenings to the inner face of the lower sash member 4 so that as the bracket slides undue wear on the window sash is prevented. This plate 22 has a toothed rack 24 arranged longitudinally thereof.

The angular member IQ of the hanger or bracket C has spaced longitudinally disposed.

slots 25 and 26 in which screws or other suitable elements 21 and 28 slide as the window sash is swung inwardly and outwardly and whereby the bracket and the window sash slide relatively to each other. The said elements 21 and 28 project inwardly from the lower member 4 of the window sash through said slots 25 and 26 and their outer projects a screw-threaded bolt or the like 30 and which slides in: the slot 29 as the window sash is moved inwardly and outwardly without interfering with said relative movement.

- A device 3| has a screw-threaded socket 32 for working screw-threaded fit with said screwt-hreaded bolt or the like 30 for operation thereon to fasten the window sash and bracket against relative movement either when the window sash is closed or open, but if desired, a supplemental latch 33 may be provided for coaction with the keeper 34 to further lock the window sash in closed position. s

A horizontally disposed swinging link 35 may be pivoted at its inner end, as at 36, to the window sill, but preferably, at the inner end of the aforesaid guide M, as shown. This link 35 at its outer end is pivoted at 35': on the bracket and it is provided at its inner extremity with a gear toothed extension or portion, 31 which is adapted to constantly mesh with the aforesaid rack 24 on the plate 22 to effect relative sliding movement of the sash and the bracket and whereby the sash is carried into and out of tight engagement with the window frame in the closing and opening of the window.

'The mounting of the lower end of the window sash will now be well understood and it seems sufiicient to merely state thatthe upper end of the sash is mounted in the identical manner by the same form of means, the bracket and guide member simply being reversed as to position.

The mounted parts at the top of the window are the same as the mounted parts at the lower portion of the window, both upper and lower parts operating in unison and in the same manner and each having the fastening'device 3|, if desired, so as to provide for effective holding of the Window sash especially when open and to prevent accidental closing or breakage in the event of sudden wind storms.

Both of the upper and lower guide members and the inner ends of the links 35 and extension 2| of the brackets C may be enclosed, if desired, by means of a metallic or other suitable plate or member 38, fastened by screws 39, if

desired.

By virtue of I the relative movement between the brackets and the window sash, the latter has both a swinging and a bodily sliding movement to and from closed positions and the windowv sash may be opened to various positions or inclinations between closed position and an outward position slightly beyond a right angle to the plane of the window frame. This affords opportunity or enables a person on the inside of a building or room to readily wash both sides of the window when open because, say for instance, when the window is swung to the position shown in Fig. 3, either or both sides of the window may be readily reached forcleaning purposes...

The various elements employed for swingingly hanging or mounting the casement window are composed of strong materials to insure against sagging of the window and to provide for such .rigidity as gives long life to the mounting and actuating parts thereof and it might be noted that by virtue of the slides l having frictional -mounting in the respective guides i l that the window may be maintained open under ordinary conditions against accidental closing without resorting to the fastening devices 3| but on account of suddenly rising winds it has been deemed adyisable to embody said fastening devices in the organization of parts constituting the present invention. If desired, the windows may be weather. stripped by means, for instance, of the metal strips 40 having ribs or edges 4| to fit ingrooves 42 in the outer side faces of the window sash when the latter is closed.

It will be understood from the foregoing that when the window is closed and latched that after unlatching the same the window may be easily swung to various open positions for ventilating purposes and when inclined with relation to the plane of the window casing the vacuum created in a room by the passing air currents is in accordance with the degree of openly-inclined position of the window and that eifective ventilation'may be thereby regulated and that under normal weather conditions the open window will be maintained in desired position by the spring- 1, obviating necessity of working the latching devices 3| unless desired to do so.

What is claimed is:

1. A mounting for a window sash comprising means for the swinging support of the window sash in a window frame, including a channeled guide on the window frame, a slide in said guide, a bracket slidably mounted at one end on the sash and pivotally connected at its other end to said slide, a-toothed rack on the sash, a link pivoted at-one. end to said guide and pivoted at its other end to said bracket and having gear teeth in constant mesh with said toothed rack, whereby upon an outward force applied to the sash thesash may be swung outwardly and said, slidemoved in said guide to give relative movement to the sash and bracket and carry the sash bodily away from the frame.

2. A mounting for a window sash comprising means for the swinging support of the window sash in a window frame, including a channeled guide on the window frame, a slide in said guide, a-bracket slidably mounted at one end on the sash and pivotally connected at its other end to said slide, a toothed" rack on the sash, a link pivoted at one end to said guide and pivoted at its other end to said bracket and having gear and means to reenforce said holding means to secure the sash against accidental closing movement.

3. A mounting for a window sash comprising a supporting means for swingingly and slidably supporting the window sash in the window frame including a bracket slidably mounted on the sash and pivotally and slidably mounted on the frame for relative movement with the sash as the sash swings outwardly and inwardly with relation to the frame, means for sliding the sash relative to the bracket during pivotal sliding movement of the latter relative to the frame, and means for restraining movement of the bracket relative to the sash to thus lock'the sash against movement relative to the frame.

4. In a mounting for casement windows, a frame-carried guide plate, a slide movable therein, a bracket having a horizontal portion pivoted at one end to said slide and having an upright flange provided with a series of slots lengthwise of the bracket, a link pivoted at one end to' one end of said guide plate and at its other end to the horizontal portion of the bracket and provided at its latter end with a toothed portion projecting through one of the bracket slots, a sash-carried plate having guide members projecting through certain of the bracket slots and supporting the upright flange of the bracket slidably against said plate, a rack carried by said plate and engaged by the toothed portion of the link to force sliding movement of the plate relative to the bracket when the latter is swung on its pivot, a threaded stud carried by the said sash plate and projecting through another slot of the bracket, and a member threaded on said stud and movable against the bracket to bind the latter against the sash plate and thus secure the parts in various adjusted positions.

5. In a mounting for casement windows, a frame-carried guide plate, a slide movable therein, a bracket having a body L-shaped in cross section including a horizontal portion pivoted at one end to said slide and an upright portion provided with a series of slots lengthwise of the bracket, a link in a single rigid piece pivoted at one end to one end of said guide plate and at its other end to the horizontal portion of the bracket intermediate the ends of the latter and provided at its latter end with a gear portion projecting through one of the bracket slots, a sashcarried plate having guide members projecting through certain of the bracket slots and supporting the upright flange of the bracket slidably against said plate, a rack carried by said plate and engaged by the gear portion of the link to force sliding movement of the plate relative to the bracket when the latter is swung on its pivot, a threaded stud carried by the said sash plate and projecting through another slot of the bracket, and a member threaded on said stud and movable against the bracket to bind the latter against the sash plate and thus secure the parts in various adjusted positions.

6. A device of the character described, comprising means for the swinging support of a window sash in a window frame, including a hinged connection between the sash and frame having a sash engaging and carrying member with respect to which the sash is constrained to slide during swinging movement, means to frictionally resist swinging movement of the sash for holding the sash in selected open position, and means for securely holding the sash against sliding movement when the sash is in open and closed positions to thus prevent its swinging move- 'ment.
